Hey Joes,

You can always burn some rubber and look at tires marks on the ground but as far as I know "no LSD" my friend.

 

I would say probably not unless, someone changed the rearend. There is other way to check for a posi without the burn out. If you can put the car in neutral and lift both rear tires off the ground. Then spin one of the tires and check to see if the other tire spins the same direction if it does you have an lsd. If it spins the opposite way you don't have an lsd. The only catch is if the car has been sitting dormant for years the rearend might give you a false lsd signal. Anyway good luck and have fun
